Additional Information

Etymology

1. c.1384, from O.Fr. acte, from L. actus "a doing" and actum "a thing done," both from agere "to do, set in motion, drive, urge, chase, stir up," from PIE root *ag- "to drive, draw out or forth, move" (cf. Gk. agein "to lead, guide, drive, carry off," agon "assembly, contest in the games," agogos "leader;" Skt. ajati "drives," ajirah "moving, active;" O.N. aka "to drive;" M.Ir. ag "battle"). Theatrical (1520) and legislative (1458) senses of the word also were in Latin. The verb is first attested 1475; in the theatrical performance sense it is from 1594. In the act "in the process" is from 1596, originally from the 16c. sense of the act as "sexual intercourse." Act of God "uncontrollable natural force" first recorded 1882. To act out "behave anti-socially" (1974) is from psychiatric sense of "expressing one's unconscious impulses or desires."
